HOSE COUPLING.

SPECIFICATION forming part of Letters Patent N 0. 628,765, dated July11, i899. Application filed April 13, 1899. Serial No. 712,906. (Nomodel.)

To on whom it may concern.-

Be it known that I, JOHN COLLETTE, a itizen of the United States,residing at Hudson, in the county ofMiddleseX and State ofMassachusetts, have invented certain newand useful. Improvements inHose-Couplers, of which the following is a specification.

Myinvention is animproved hose-coupling; and its object is to provide aconstruction which will make a close locking-joint between the membersof the coupling and prevent the ingress of sand, grit, or the likebetween the adjacent faces of the parts, as now frequently occurs, withthe result that these faces are quickly worn out of aline, a close fitis prevented, and the coupling rendered ineffective and leaky.

By my improved construction I place a spring tension or pressure uponthe adjacent faces of the coupling, keeping them always in contact andat the same time adding to the safety of the lock between the parts.

In the accompanying drawings, Figure 1 is a sectional VlGW' through thecoupling, showing parts in elevation. Fig. 2 is a detail face View ofone part, and Fig. 3 a perspective View of the other part.

The ring A has a threaded extension at, to which is secured the collar1), of ordinary construction and adapted for connection with one end ofthe hose. To the front face of the ring A is secured a compound ringmade up of two flanged parts B C, the ring B having anoutwardly-extending flange secured to the face'of the ring A by screws0. The ring 0 fits upon the periphery of the ring 13 and has a flange (Zoverhanging the front edge of the ring B. The parts of the compound ringare secured together loosely to prevent separation by pins 6 on theinner face of the ring 0 entering elongated slots in the ring B, whichwhile preventing disengagement of the parts allows of a certain amountof movement relatively to each other for a purpose hereinafter referredto. The ring B is provided with longitudinal openings g extending fromfront to rear, and these openings contain spring-pins h, the outer endsof which bear against the inner face of the flange d and tend to forcethe ring 0 outwardly in relation to the ring B. The rear ends of thespring-pins find resistance against the face of the ring A.

V The ring A has a shoulder to receive a gasket i and also aninwardly-extending annular flange Z, which is cut with bayonet-jointnotches adapted to receive the lugs m on the oppositecoupling-section D.The spring-pins h tend to throw out the face of the ring 0 beyond theouter edge of the flange Z, and when the parts are placed togethersufficient pressure is necessary to force in the ring 0 slightly topermit the lugs m to engage the bayonetjoints of the flange l, and assoon as the parts engage the spring-pins put apressure upon the parts,forcing out the ring 0 into close contact with the flange n of thecoupling D, resisting any tendency to separate and preventing grit fromentering between the opposing faces. The spring tension also rendersmore secure the locking action, as the projections 0 of the joints haveslight inwardly-extending projections 12, and to disengage the partsinward compression of the coupling-sections is necessary.

What I claim is- 1. Acoupling comprising aring A, a second ring securedthereto, a third ring having loose connection with the second ring,springs between the second and third rings, a lockingflange carried bythe first ring and a second section having lugs to engagethelockingflange, substantially as described.

2. A coupling comprising a ring A, a compound ring secured thereto, theparts of said compound ring being loosely connected, springs between theouter member of the compressed ring and the ring A, a locking-flangecarried by the ring A and a second section having lugs adapted to engagethe lockingflange and having a flange to contact with the face of thespring-pressed ring, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

hi JOHN COLLETTE.
